Final answer:
Nonpharmacological pain control interventions aim to refocus the patient on positive stimuli and promote relaxation, but they do not directly reduce pain. They are used in conjunction with analgesic medications.
Step-by-step explanation:
Before introducing nonpharmacological pain control interventions into the patient's plan of care, the nurse should teach the patient that these interventions will not directly reduce pain, but will refocus the patient on positive stimuli. Nonpharmacological interventions include techniques such as distraction, relaxation therapy, and guided imagery, which aim to distract the patient's attention away from pain and promote relaxation. While these interventions can be effective in managing pain, they do not eliminate the need for analgesic medications.
